To all whom it may concern:

Be it known that I, JAMEsD. JACKSON, a citizen of the United States,residing at Washington, in the District of Columbia, have invented newand useful Improvements in Disinfecting Attachments for Sewers, Sinks,Sto., of which the following is a specification.

My invention relates to disinfecting attachments for sewer-openings, theobject being to provide a simple device for absorbing and deodorizing ordisinfeotin g the escaping gases from sewers; andthe invention consistsin a foraminons box or receptacle for broken charcoal or otherdisinfectant or deodorizing material, which device is pivoted insuitable bearills@ at the. .eutrancesnexitsxotseners. orsewer-connections in such a manner aste act as a valve to normally closesuch openings and absorb the intercepted gases and odors, and yet havesnicient movement to permit the hereinafter more fully set forth.

In the accompanying drawings, which fullyillustrate my invention, Figurel is a sectional View of a street-sewer catchbasin or trap with mydisinfectant attachment in position. Fig. 2 is a perspective View of theforaminous box or cage for holding the disinfectant material;

porting the box or cage; and Fig. 4 is a transverse vertical sectionalview through the box or cage.

Like letters indicate like parts. A The disinfectant-receptacle Aconsists of a narrow box or cage having foraminous sides a, adapted topermit the passage of air or gas. This cage is lled with broken charcoalorother suitable disinfectant material, which may be readily changed orrenewed from time to time, as required. The box A is provided with acover, @which is slotted at each end to engage with perforated lugs c c,the cover being held in place by pins d d passing through the lugs. teach end of the box is a pivot, e, by which the receptacle is journaledin inclined slots j' f, formed in the bearingpiates B B at each side ofthe sewer-opening.

When in position the disinfectant-box A'ts be connected above by atransverse piece, B', 5o

that forms a seat for the upper rear portion of the box when thesewer-openingis closed. In closingathe sewer-opening the box A is alsoseated anteriorly against a shoulder, C, at the lower edge of saidopening.

' It will thus be seen that the box or cage A acts as a valve to closethe mouth ofthe sewer, while the disinfectant material, D, contained inthe box is in such position as to intercept and absorb the deleteriousgases and odors that seek an escape thronghthe sewer-opening.

It will also be observed that while the box or cage is hung in such away as to normally closethe sewer-opening it will readilyopen inwardatitslower edge on recel-vin g the slightest pressure of wateren teringthe sewer-month or streetjnlet E. As the lower edge of the box thusmoves backward under the pressure of incoming water its upper portiontilts forward until `its anterior face rests on the inclined guard Fabove the sewer-inlet. In this position, while the sewer-openingislilled with incoming water, the escape otlgases. above is d prevented bythe-contact of theposterior face of the disinfectant-box with the loweredge ot the transverse frame or shoulder B', that 'extends between thebearings B B. The manner in which the disinfectant-box is arranged withrelation to the streetrinlet enables it to be readily removed andreplaced by simply raising the cap-plate G and lifting the box out oragain loweringr it in position, as required.

It is obvious that the disinfectant-box may be composed of any suitablematerials, or made in any oonienient shape to conform to the shape andsize of the openings which it is designed to guard.

The invention may be applied not only to the street-inlets of sewers,butalso to water-closets, f

sinks, privies, and Ventilating-pipes with only 'f slight modifications.

Where the flow of water is insufficient .to operate the device it may beprovided with rods or chains arranged to open and close the pas sageswithout departing fromthe spirit of my invention, the essential featureof which consists in applyingto sewer openings or passages snuglybetween its hearings B B, which may through which noxious gases andvapors are exhaled atrap or valve composed of aforalniterial,pivotedinsuitable bearings, and forming r 5 nous receptacle containing n suitable'disinavalve for intercepting and absorbing gasesiu fectant materialadapted to absorb and destroy sewers and sewenconneqions, substantiallysuch deleterious exhalations. as described.' f4
